  1. 1. Prosody and emotion: Towards the development of an emotional agent Emotional evaluation of news reports: production and perception experiments

    University essay from Göteborgs universitet / Institutionen för filosofi, lingvistik och vetenskapsteori

    Author : Liina Tumma; [2022-01-20]
    Keywords : emotion; speech; prosody;

    Abstract : There is a recognised need for more research on the topic of emotion recognition from speech, and clear and defined methodology in this area is still lacking. Most studies in the field of emotional speech recognition and classification usually focus on acted speech as the data source;consequently, other methods that capture more natural speech are left aside.

  2. 2. Piezoelectric Guitar Tuner

    University essay from KTH/Mekatronik; KTH/Mekatronik

    Author : Albin Boestad; Fabian Rudberg; [2021]
    Keywords : Mechatronics Tuner Guitar Piezo Arduino; Mekatronik; Stämmare; Guitar; Piezo Arduino;

    Abstract : This bachelor thesis in Mechatronics account for the process of constructing an automatic guitar tuner by means of a piezo-electric sensor, a stepper motor and Arduinobased control. The E4 - string on an acoustic guitar was used as a proxy for tuning any other possible guitar string. READ MORE

  3. 3. Capacitive Micromachined Ultrasonic Transducers for Underwater Applications

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Patrick Johansson; [2021]
    Keywords : CMUT; capacitive; micromachined; ultrasonic; transducer; model;

    Abstract : Capacitive micromachined ultrasonic transducers (CMUT:s) are often used in medical imaging and they show some promise as underwater transducers. This thesis collates the available information about how CMUT:s operate, their strengths and weaknesses and investigates their efficiency as an underwater transducer. READ MORE

  4. 4. Attenuation of bending waves in cross-laminated timber panels by using constrained damping layer

    University essay from Luleå tekniska universitet/Träteknik

    Author : Konrad Boeske; [2021]
    Keywords : Wood technology; damping; CLT; acoustic; low frequencies; AkuTimber;

    Abstract : Multi-storey wooden buildings become more and more popular. As the new housing solutions are more accessible, acoustical inconveniences of wooden buildings become actual as never before. Wood, thanks to its high stiffness and low mass, allows to erect buildings at impressive pace, albeit cannot damp low frequency noises efficiently. READ MORE

  5. 5. Experimental Study of Installation Effects on Cooling Fan Noise

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : Yu-Yu Lu; [2021]
    Keywords : Electric vehicles; Cooling fan noise; Installation effects; Free-space measurement; Wall-mounted measurement; In-vehicle measurement; Spectral decomposition method; Tonality; Broadband noise level.;

    Abstract : Owing to the ever-changing developments of battery and electric powertrain, vehicle electrification is the trend in the future. Without the presence of a combustion engine, masking effect from it reduces and noises from other components become perceivable. Among all, the cooling fan is one of the major noise sources. READ MORE
